For decades, chlorine has been used to keep swimming water healthy, even with public pools that serve dozens of swimmers a day. Some modern pools use a combination of salt and chlorine to reduce the harsh effects of the chemicals, but even then, chlorine does most of the heavy lifting.

But chlorine has its limits. That’s why pools combine chlorine with filters to keep water as crystal clear as possible. The filter pulls dirt and debris from the water to allow the chlorine to working on keeping bacteria to a minimum. But as the pool is used each day, the chlorine has to work hard to kill all that bacteria, which can tax it. For that reason, the CDC urges pool owners to regularly test the water’s free chlorine, as well as its pH. This will help eliminate the bacteria, viruses and parasites that can thrive in stagnant water.

Even if you pay a service to handle this for you, you’ll need to keep an eye on things between visits to make sure your water remains safe for your loved ones.

Although swimming is certainly nothing new, it’s only in relatively recent times that chlorine has been used to reduce bacteria in communal waterways. In the late 1800s, the idea of adding chlorine to pools to help clean them was first proposed, but it wasn’t until it became necessary for public safety that the practice caught on.

Typhoid fever is to credit for the widespread use of chlorine. A 1905 outbreak in England was caused by a defective sand filter in a pool. Soon after, chlorine was not only added to pools in Europe, but also in the U.S., where New Jersey added it to the Boonton Reservoir. It wasn’t until the mid-1900s, though, that a full understanding of the benefits of chlorination and filtration made it possible for swimming to become a popular pastime.
